{"id":"UBUNTU-CVE-2026-73515","details":"PostGIS before 3.7.0beta2 contains an out-of-bounds read vulnerability that allows attackers to cause memory disclosure or a server crash by supplying a malformed FlatGeobuf buffer. The FlatGeobuf property metadata decoder verifies that a string length field is present but fails to verify that the subsequent string body is contained within the supplied buffer before materializing it into a SQL-visible value, enabling memory disclosure or denial of service.","modified":"2026-08-19T13:34:11.336951836Z","published":"2026-08-13T16:19:00Z","upstream":["CVE-2026-73515"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-73515"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-73515"}],"affected":[{"package":{"name":"postgis","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/postgis?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.8+dfsg-4","2.2.0+dfsg-1","2.2.0+dfsg-3","2.2.1+dfsg-1","2.2.1+dfsg-2","2.2.1+dfsg-2ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"liblwgeom-2.2-5","binary_version":"2.2.1+dfsg-2ubuntu0.1"},{"binary_name":"postgis","binary_version":"2.2.1+dfsg-2ubuntu0.1"},{"binary_name":"postgresql-9.5-postgis-2.2","binary_version":"2.2.1+dfsg-2ubuntu0.1"},{"binary_version":"2.2.1+dfsg-2ubuntu0.1","binary_name":"postgresql-9.5-postgis-scripts"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73515.json"}},{"package":{"name":"postgis","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/postgis?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.3+dfsg-1","2.4.2+dfsg-1","2.4.2+dfsg-2ubuntu2","2.4.2+dfsg-3","2.4.3+dfsg-2","2.4.3+dfsg-3","2.4.3+dfsg-4"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.3+dfsg-4","binary_name":"liblwgeom-2.4-0"},{"binary_name":"postgis","binary_version":"2.4.3+dfsg-4"},{"binary_name":"postgis-gui","binary_version":"2.4.3+dfsg-4"},{"binary_version":"2.4.3+dfsg-4","binary_name":"postgresql-10-postgis-2.4"},{"binary_name":"postgresql-10-postgis-2.4-scripts","binary_version":"2.4.3+dfsg-4"},{"binary_name":"postgresql-10-postgis-scripts","binary_version":"2.4.3+dfsg-4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73515.json"}},{"package":{"name":"postgis","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/postgis?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.3+dfsg-1","3.0.0+dfsg-2ubuntu1","3.0.0+dfsg-6ubuntu4"],"ecosystem_specific":{"binaries":[{"binary_version":"3.0.0+dfsg-6ubuntu4","binary_name":"postgis"},{"binary_name":"postgis-gui","binary_version":"3.0.0+dfsg-6ubuntu4"},{"binary_name":"postgresql-12-postgis-3","binary_version":"3.0.0+dfsg-6ubuntu4"},{"binary_name":"postgresql-12-postgis-3-scripts","binary_version":"3.0.0+dfsg-6ubuntu4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73515.json"}},{"package":{"name":"postgis","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/postgis?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.1+dfsg-1","3.1.4+dfsg-3ubuntu2","3.2.0+dfsg-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.2.0+dfsg-1ubuntu1","binary_name":"postgis"},{"binary_name":"postgresql-14-postgis-3","binary_version":"3.2.0+dfsg-1ubuntu1"},{"binary_name":"postgresql-14-postgis-3-scripts","binary_version":"3.2.0+dfsg-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73515.json"}},{"package":{"name":"postgis","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/postgis?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.3+dfsg-2ubuntu1","3.4.0+dfsg-4ubuntu1","3.4.1+dfsg-1ubuntu1","3.4.2+dfsg-1ubuntu1","3.4.2+dfsg-1ubuntu2","3.4.2+dfsg-1ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.2+dfsg-1ubuntu3","binary_name":"postgis"},{"binary_name":"postgresql-16-postgis-3","binary_version":"3.4.2+dfsg-1ubuntu3"},{"binary_name":"postgresql-16-postgis-3-scripts","binary_version":"3.4.2+dfsg-1ubuntu3"},{"binary_version":"3.4.2+dfsg-1ubuntu3","binary_name":"postgresql-postgis"},{"binary_name":"postgresql-postgis-scripts","binary_version":"3.4.2+dfsg-1ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73515.json"}},{"package":{"name":"postgis","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/postgis?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.3+dfsg-2build1","3.6.1+dfsg-1build1","3.6.2+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"postgis","binary_version":"3.6.2+dfsg-1"},{"binary_version":"3.6.2+dfsg-1","binary_name":"postgresql-18-postgis-3"},{"binary_version":"3.6.2+dfsg-1","binary_name":"postgresql-18-postgis-3-scripts"},{"binary_name":"postgresql-postgis","binary_version":"3.6.2+dfsg-1"},{"binary_name":"postgresql-postgis-scripts","binary_version":"3.6.2+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/ma
